Though some drugs and medical conditions have been linked with male breast enlargement, sometimes there is no known cause for this condition. It may occur in one or both breasts.  There are two types of Gynecomastia: primary and secondary. Primary Gynecomastia usually develops during puberty. There is no underlying cause for primary Gynecomastia.

Secondary Gynecomastia develops because of some underlying cause. Causes of secondary Gynecomastia include obesity and the use of certain drugs such as steroids, alcohol or marijuana. If a patient is obese, drinks alcohol in excess, smokes marijuana or takes steroids, they will be discouraged from having surgery and asked to stop using these drugs to see if breast fullness is reduced.

The best candidates for this surgery have firm, elastic skin that will reshape itself to a new contour after surgery.

Surgery for Gynecomastia is performed as an outpatient procedure. The surgery itself takes about an hour and a half. Correction of enlarged male breasts is usually performed under a general anaesthetic. The surgery to correct male breast enlargement removes fat and/or glandular tissue from the breasts. In some cases where large amounts of fat or tissue are removed, the skin may not adjust well to the breast contour. If this occurs, excess skin may be removed to allow the breast to adjust to its new shape.

Complications related to surgery are infrequent and usually minor. The risks associated with this surgery include developing an infection, excessive bleeding, and excessive fluid accumulation. Noticeable scars can also result from this surgery, as can permanent pigment changes in the breast area, or asymmetric breasts or nipples. If asymmetry is significant, a second procedure may be performed.

The temporary effects of male breast reduction surgery include numbness which may last up to a year.

To help reduce swelling, you will be advised to wear an elastic pressure garment for a few weeks after th surgery.

You can expect to be back to normal daily activities within a week but you will be restricted from heavy physical activity for about a month. It will take about 3 months before you see the final result of your surgery.
